Re: What do the names Felisberto and Felisberta mean?
The usual etymology for Filibert assumes a purely Germanic origin and identifies the prototheme Fili with Modern High German viel "much, many". But there is a connection between Filibert and Phillip, and Filibert is seen as a door-opener for the foreign name Phillip that was one of the first foreign names to be adopted by people in Germany. A similar relation is assumed for Sigmund and Simon.

the prototheme connected with viel is Felu-, continental filu- is anomalous, characteristic of East German, not West-Germanic. Vili occurs in OHG, but doesn't appear to be normal.

At some point in history (Ostrogothic Kingdom at Verona, Italy), East Germanic and Bavarian were geographically adjacent, and there are some Gothic loan words in German, and some Greek words transmitted via Gothic. So such kind of connection is not too far fetched.
